Synthetic Mineral Mica Powder Pigment
Synthetic mica is also known as fluorophlogopite. It is prepared by high temperature melt cooling and crystallization of chemical raw materials. Its single wafer has a fraction of KMg3(AlSi3O10)F2, which belongs to monoclinic system and is a typical layered silicate.
The performance of synthetic mica powder is much better than that of natural mica. For example, the temperature resistance is up to 1200 °C. Under high temperature conditions, the volume resistivity of synthetic fluorophlogopite is 1000 times higher than that of natural mica. The electrical insulation is good, and the vacuum vent is high. Low, acid and alkali resistant, transparent, separable and elastic, it is an important non-metallic insulating material for modern industries and high technology such as motors, electrical appliances, electronics, and aviation.
More than 95% of the synthetic mica crystal blocks obtained by the internal thermal method are small crystals, ie, synthetic mica fragments, which can be used to make a variety of insulating products, such as synthetic mica paper, laminates, fluorophlogopite mica powder, mica pearlescent pigments. And mica ceramics, etc. Our factory mainly produces synthetic mica broken. 20 mesh. 40 mesh. 60 mesh. 100 mesh. 200 mesh. 300 mesh. 400 mesh. 600 mesh and other mica powder.
Mica Powder Application:
It is widely used in electrical appliances, welding electrodes, rubber, plastics, paper, paints, coatings, pigments, ceramics, cosmetics, new building materials and other industries. With the continuous development of science and technology, people have opened up new fields of application.
